Digital Camera World Verdict

Think ultra-wide-angle lenses and you’re probably thinking of hefty beasts that weigh you down. This Sigma is something altogether different. Thanks to a modest f/4 aperture rating and clever design-work, this 17mm full-frame compatible lens is outrageously small and lightweight for its type, but impeccably engineered and a high-flyer in terms of image quality. And it comes with a very attractive price tag.

Pros

  • +

    Robust all-metal build

  • +

    Aperture control ring

Cons
